You are using Newton's method to solve x35x2=0. If your first guess is x1=2, what value will you calculate for the next approximation x2?

PhysicsPro,
your equation would be
xnew = x  (x^3  5x  2)/(3x^2  5)
so for x=2
xnew = 2  (8102)/(125)
= 2.5714
Incidentally, my next 4 answers were
2.4268029
2.4143045
2.4142136 and
2.4142136 which would be one of the answers correct up to 7 decimal places.
